I gave birth almost 5 years ago and since then my immune system just was not what it was. I was getting ill almost every month (honestly, I felt like a three year old) and in the winter I was, at least once, getting a flu with fever (before birth I rarely got a cold and fever???...did not exist in my lexicon for years). I bought this multi vitamin in despair to try to pass this winter without too many colds, especially because the last time my cold turned into severe sinusitis - never had one of those in my life! I was not disappointed. I am so happy I bought this multi vitamin. I feel like my immune system got back. I got a sore throat only twice and it lasted exactly 3 days each time! I can definitely manage that :). And that is without taking all the recommended quantity; I take only one pill a day. I'll buy this one every autumn to be ready for winter! Great stuff! Thank you FutureBiotics!
